It's confusing. Questing is a grind so people want a return to Sandbox style MMO's where you can do whatever you want. Sandbox MMO's generally require lots of undirected grinding to get the resources you need to accomplish whatever you want.
Either way it's a grind. Some people want their grind to be their choice and other people want it directed...and still other people don't care as long as the systems are well designed and fun (That's me personally).
Even if there's a game that levels you by a press of a button, people will still complain that it's a grind.
People are dumb.
